## En Detalle

El marcador `@pytest.mark.anyio` le dice a pytest que esta función de test debe ser llamada asíncronamente:

{* ../../docs_src/async_tests/test_main.py hl[7] *}

/// tip | Consejo

Note que la función de test ahora es `async def` en lugar de solo `def` como antes al usar el `TestClient`.

///

Luego podemos crear un `AsyncClient` con la app y enviar requests asíncronos a ella, usando `await`.

## `Request`-Dokumentation

Weitere Details zum <a href="https://www.starlette.io/requests/" class="external-link" target="_blank">`Request`-Objekt finden Sie in der offiziellen Starlette-Dokumentation</a>.

/// note | Technische Details

Sie können auch `from starlette.requests import Request` verwenden.

**FastAPI** stellt es direkt zur Verfügung, als Komfort für Sie, den Entwickler. Es kommt aber direkt von Starlette.

Вы можете использовать функцию `Field` с атрибутами модели:

{* ../../docs_src/body_fields/tutorial001_py310.py hl[9:12] *}

Функция `Field` работает так же, как `Query`, `Path` и `Body`, у неё такие же параметры и т.д.

/// note | Технические детали

На самом деле, `Query`, `Path` и другие функции, которые вы увидите в дальнейшем, создают объекты подклассов общего класса `Param`, который сам по себе является подклассом `FieldInfo` из Pydantic.
